Our last crack at ranking college basketball’s top recruiting classes came in August. Plenty has changed since then.

- Memphis continued adding to its backcourt riches.

- Star Phoenix wing Daniel Bejarano reneged on his pledge to Texas (making that the last Longhorn reference in this article).

- Kyrie Irving made Duke fans happy.

- And Kevin O’Neill has somehow pieced together an exciting cast of athletes at USC.

But the team at the top hasn’t changed – at least not yet.

Ohio State still has commitments from four members of the MaxPreps.com 2010 Top 100, including Top 10 prospects Jared Sullinger and DeShaun Thomas. Thad Matta also has pledges from two other highly-regarded preps and expects to sign all six this week.

The early signing period for college basketball begins today and runs through Nov. 18. It’s not quite the holiday that football signing day has become as many prospects will wait to sign or even make a decision until the second wave running from April 14 to May 19, 2010.

Duke could emerge as the Buckeyes’ primary challenger if they get a commitment from Iowa star Harrison Barnes, who has scheduled an announcement for Friday that will air live on ESPNU.

Without regard to Barnes’ decision, or any other potential developments, here is MaxPreps.com’s look at college basketball’s top 25 recruiting classes entering Wednesday;

8. North CarolinaTop 100: No. 5 Reggie Bullock (6-7, 190, W), No. 13 Kendall Marshall (6-3, 175, G)Analysis: Tough to decide where to put the Tar Heels with just two commitments. After bringing in a number of quality post players last year, Roy Williams went hunting on the perimeter and came up with a pair of big-time talents. Landing Barnes on Friday isn’t out the of question.

13. North Carolina StateTop 100: No. 38 Luke Cothron (6-8, 220, F), No. 39 Ryan Harrow (6-1, 150, G)Supporting Cast: Lorenzo Brown (6-4, 175, G/Post-graduate)Analysis: Brown was expected to be on campus this fall, but is instead spending the year at Hargrave Military Academy in Virginia and will join Cothron and Harrow as freshmen in 2010-2011.

16. UCLATop 100: No. 6 Joshua Smith (6-10, 280, F), No. 93 Tyler Lamb (6-5, 205, W)Analysis: A Kevin Love-type impact isn’t out of the question with Smith, but improving his conditioning is a must. The Bruins could use another guard. Ray McCallum would be a nice fit.
